Savings
Congestion
• Wasted bandwidth: retransmission of dropped packets
• Poor user service : unpredictable delay, low user goodput
• Increased load can even result in lower network goodput
– Switched nets: packet losses create lots of retransmissions
– Broadcast Ethernet: high demand -> many collisions
